WOOD-WORKING MACHINE.

SPECIFICATION forming part of Letters Patent N0. 468,897, dated February 16, 1892.

- Application filed February 20, 1891. Serial No. 382,184. (No model.)

To all whom it may concern:

Be it known that we, FREDERICK RICH, a citizen of the United States, and NICOLAS SONDAG, a citizen of France, both residing at St. Louis, in the Stateof Missouri, have invented certain new and useful Improvements in Wood-Torking Machines, of which the fol# lowing is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part hereof.

Our invention'relates to improvements in wood-working machines; and it consists in the novel arrangement and combination of parts, as will be hereinafter more fully described, and designated'in the claims.

In the drawings, Figure 1 is a top plan view of our complete invention, showing a piece of wood in position to be worked upon. Fig. 2 is a vertical cross-section taken on the line :c :r of Fig. 1. Fig. 3 is a side elevation of our Figi is a longitudinal vertical section of our invention. Fig. 5 is a vertical cross-section of the gaging mechanism. Fig. Gis a cross-section on line 6 6 of Fig. 3.

The object of our invention is to construct a machine for workingl wood, and especially designed for mortising or grooving planks in the construction of steps, stoops, dac., and for various other purposes too numerous to mention.

Referring to the drawings, 1 indicates the horizontal table-supports. Said supports are firmly secured at their lower extremities to any support on which it is adapted for the operatingmechanism of ourmachinetobeplaced. Said supports l arelaterally secured together orbraced by means of a horizontal cross-piece 2. This cross-piece 2, as well as the supports 1, may be constructed in any iinished form according to the taste and judgment of the manufacturer. To the upper portions of said upright supports are adjustably secured wedge-'shaped sliding plates 3. Said plates are provided with elongated slots 4, through which slots thumb-screws 5 pass, thereby holding and adj ustably securing said plates 3 to the upright supports 1. Said plates are movable in a forward and backward direction, this forward and backward motion, however, being effected by means of a screw-threaded shaft 6, the front end of which has secured to it a wheel 7, and the opposite end is providedV with screw-threads and adapted to be screwed in a screw-threaded perforation formed in a horizontal cross-piece 8, the ends of which are rigidly secured to upright supports 1. Said shaft has its bearings in a horizontal crosspicce 9, the ends of which cross-piece are rigidly secured to the wedge-like sliding plates 3. Said horizontal cross-piece 9 is provided with a bearing projection 10, Which is interposed between collars 11, rigidly secured to shaft 6. By rotating Wheel 7, and consequently shaft 6, to which said wheel is rigidly secured, the wedge-shaped sliding plates 3 are adj usted or moved in a forward or rearward direction.

12 indicates a horizontal table, which yis movably secured to the sliding wedge-shaped plates 3 in any suitable and mechanical manner, and is adjustable in a forward or rearward direction-as said wedge-shaped sliding plates are adjusted, as hereinbefore stated. As said wedge-shaped plates are pushed forward, from the peculiarity of their construction, of course,the horizontal table 12 will be elevated, and by moving said sliding platesin an opposite direction as a natural consequence said table will be lowered, the'extent of the elevation and depression-of said table of course corresponding to the excess of the inequality of the Width of the opposite ends of said slid# ingplates 3.

13 indicates a rotating table, which is pivotally secured and mounted on table 12 in the following manner, to Wit: Table 12 has formed in it a conical depression 14, in which depression a conical projection 15, formed ou table 13, is adapted to snugly tit. Said projection has rigidly secured to it a screwthreaded stud 16, on the screw-threaded portion of which a small tightening-wheel 17 may be screwed. Said stud 16 has its bearing in a U-shaped plate 18, which is rigidly secured to the bottom of table 12. The frontfportion of table l2 vis provided with an L-'shaped bar 19, over which bar a bar 20, provided with a dovetailed groove, may be slipped, and is adv justable thereon, the desired adjustment being effected by meansof aset or thumb screw 21, which is adapted to pass through the upper portion of bar 2O and impinge on the up per surface of the L-shaped bar 19. The L- shaped bar 19 and the adjustable bar 20, movable along the same, is used for adjusting the work cndwise when it is not desired to gage, as hereinafter explained.

IOO

when it is moved itself, and by this means the vcally arranged relative to each other.

distance between grooves maybe adjusted.

As the table 13 is not laterally adjustable, it is'absolutely necessary that a construction like the one just described or one similar thereto should be used for effecting this lateral adjustment. The rotating table V13 is to .adjust `and regula-te the angles `of the grooves or mortises.

24 .indicates-a gaging mechanism ordevice by which we set off and regulate the exact dis- -tance between the grooves, thereby making them all of the same distance apart. Said device consists of perforated ears 25, which are firmly secured to bar 20, a small shaft 26, mounted in said perforated ears, provided .with an angular perforation through which a'small angular rod 27 `is adapted to pass,

.and is adjustably secured in Ythe same -by means of a thumb or set screw 57, an adjustable disk 28, secured to Vone end of said rod 27 by meansof a set-screw 29, and a spring 30, thefunction vof which `is to press zu'pupon rbar27 and holddisk 28 in lengagement with the grooves. Said disk .28 can be regulated oradjusted at an Aangle corresponding tothe anglesof the grooves that are cut and is adapted to fit down in said grooves. In order to disengage .said disks with the grooves, it isonly necessary to press down on handle 31 of .the bar or lever 27. When the 4first groove, 32 for instance, referringto Fig. 1, has .been cut inthe strip of wood 22, thedisk 28 is `placed in the same and another groove or .mortise is cut and the stick yof wood -is movedso thatsaid disk 28 may .beplaced in said groove. By this means the exact distance .between the grooves or mortises may be adjusted or regulated.

33 indicates a vertical column for the sawing Aand cutting `mechanism of Your device. Said lcolumn `33 is v-preferably hollow, and located in the same `are belt-pulleys 35, verti- The upperof said pulleys has secured to it on the exterior of said vertical support a-bevel gear- :pinion 36, for the purposes hereinafter more .fully specified.

37 indicate supporting-arms, which project horizontally from said column, andv secured .in the front `terminal `portions thereof is a Aend of which is secured in any mechanical manner a boring-bit 42. Said shaftis revolubly mounted in bearings 43, which bearings or boxings are secured in the vertical support 33. Said vertical shaft 41 is adjustable in a vertical direction.

44 indicates a bevel gear-Wheel, which is mounted on shaft 41 in such a manner that it may slide thereon; but it is prevented from revolving independent of the shaft by means of a lug or key 41a, secured to said shaft and entering a slot in the gear. The objecty of this construction will be readily understood when it is remembered `that the shaft fmust have vertical movement asitcarries 'the bit, and thegear 44 mustalways mesh with gear 3G. The Vertical adjustmentof said AVertical shaft 41 is effected by meansof a lever 45,one arm of which issecuredto the lupper .portion of said vertical-shaft 41 inany suitableandl mechanical manner so as not to interferewith therotatiug or revolvingof said vertical shaft 41. The other arinofsaidlever 45 `has secured thereto the gravity-'weight 46, .which depresses said .ai-mand Velevates athe -vertiealshaft 41 when in use,'as desired `by the operator.

47 indicates a table-support, which is situated vertically-under .boring-bit 42 .and `secured to :vertical support 33 .in any sui-table and .mechanical manner, on which support the Imater-ial to be worked .isplaced Having described themeehanicaljparts of our invention, we willnowfproceed-to describe the-operation of :the same.

structing stair-Ways, steps,-stoops, &c.,.thfe operator can proceed immediately yWithout layingoff the distancesapart of the-grooves-or IOO 1f itis desired to v cut out mortises or .grooves in vplan-ks inconmortises. Ourinventionisespeciallydesigned l `to do away with the marking or laying off ofthe distances between the grooves ormorti-ses lbeforecutting the same. After the firstfgroove .is cut,.whicl1 can be cutat any desiredangle .by manipulating `the rotating table 13.tl1e
